Incidentally, unlike what an earlier poster was told on the phone, the agent I dealt with said that flights can be rebooked again or cancelled fee-free after being changed for as long as the policy is in operation (subject to fare difference). At the moment that is until 30 June, but of course circumstances nearer the time may or may not extend that.
